Sonnet BioTherapeutics Collaborates With Spanios On Non-Clinical Study Using NAM-Based PDT Platforms That Emulate TME Ex Vivo To Evaluate Effect Of SON-1010 In Soft Tissue Sarcoma

Author: Benzinga Newsdesk | October 15, 2025 10:05am

Sonnet BioTherapeutics Holdings, Inc. (NASDAQ:SONN) is collaborating with Spanios on a non-clinical study using New Alternate Methodologies (NAM)-based patient-derived tumoroid (PDT) platforms that emulate the tumor microenvironment (TME) ex vivo to evaluate the effect of SON-1010 (IL-12-FHAB) in soft tissue sarcoma. The study aims to speed up the development of treatments for patients with rare and difficult-to-treat cancers.

This study utilizes Spanios' advanced patient-derived tumoroid COMPASS platform, which is engineered to closely replicate the TME, along with physiological oxygenation that can influence cancer progression and treatment response. In contrast to conventional preclinical models—often based on animal testing and less representative of human biology—patient-derived tumoroids preserve the distinct genetic and environmental attributes of individual tumors. By replicating the different pH and oxygen concentrations ex-vivo, using our COMPASS platform with our NAM-based methodology, we seek to enhance the understanding of SON-1010's efficacy against cancer cells. This approach is anticipated to yield more accurate and dependable predictions regarding the clinical performance of SON-1010 therapy. Through the integration of these innovative techniques, Sonnet intends to expedite the development of effective therapies for multiple rare and difficult-to-treat cancers, ultimately providing new options for patients with limited treatment paradigms.
